1 Beginning of the year Equity    43,704      43,704    43,704     43,704
2 Owner's investment (+)                 -         -           45,000      35,000

4 Net income / loss (+)               34836     45,036     -10164       10,036
5 End of the year Equity          78540      78540      78540      78540
Explanation:
Equity = Assets - Liability
Beginning of the year = 76500 - 32796 = $43,704
End of the year = 132000 - 53460 = 78540
 Net income = End of year equity -  (Beginning of the year Equity + Owner's Investment - Dividends)
a) Net income = 5 -  (1 + 2 - 3)
                    = 78540 - (43704  + 0 - 0)
                    = 34,836
b) Dividend of 850 per month = 850 * 12 = 10,200
Net income = 5 -  (1 + 2 - 3)
                    = 78540 - (43704  + 0 - 10200)
                    = 45,036
c) Net Income = 5 -  (1 + 2 - 3)
                        = 78540 - (43704  + 45000 - 0)
                        = -10,164
d) Dividend of 850 per month = 850 * 12 = 10,200
 Net Income = 5 -  (1 + 2 - 3)
                      = 78540 - (43704  + 35000 - 10200)
                        = 10,036
Owner's investment increases equity
Dividends reduce equity
Net Income increases equity
